Gamma Case questions

Can you still get the Gamma Case from weekly drops?

No. It is out of the weekly drop pool, so the only way to get one now is to buy it from another player or a marketplace.

What is the rarest item in the Gamma Case?

Knives are the rarest drop, at 0.26% for any of the 30. Within those, rarity comes from finish and pattern: a Karambit | Gamma Doppler Emerald is the most valuable thing it can produce right now.

Why is the Gamma Case so expensive?

It no longer drops, so no new copies enter the market while players keep opening the ones that exist, and its rare special slot includes the Bayonet, Flip Knife, Gut Knife.

Can you trade up to a Gamma Case knife?

Yes. Covert skins from The Gamma Collection can be traded up into one of the case's 30 knives, chosen at random.

Do Gamma Case skins come in StatTrak™?

Yes. Every skin and knife in the case can drop as StatTrak™, about 1 in 10 drops. Souvenirs are not case drops; eligible guns can also exist as Souvenir-O-Matic conversions.
